APPARATUS FOR USE IN PRINTING LETTERS OR OTHER INDICATIONS FOR INDIC ESOF BOOKS, &c.

SPECIFICATION forming part of Letters Patent No. 522,890, dated July 10,1894.

Applieationfiled February 23, 1894. Serial No. 501,211- (No model.)Patented in England January 26, 1893, No. 1,790: in France July 22,1893,1lo. 231,693, and in Belgium July 24,1893,No.105,882.

Be it known that I, EDGAR ALFRED GODDIN, engineer, a subject of theQueen of Great Britain, residing at 138 Brooke Road, Stoke Newington, inthe city of London, England, have invented certain new and usefulImprovements in Means or Apparatus for Use in Printing Letters or otherIndications for the Indices of Books and other Purposes, (for which Ihave received Letters Patent in Great Britain, No. 1,790, dated January26, 1893; in France, No. 231,693, dated July 22, 1893, and in Belgium,No. 105,882, dated July 24, 1893;) and I do hereby declare "that thefollowing is a full, clear, and exact description of the invention,which will enable others skilled in the art to which it appertains tomake and use the same. 1

These improvements have reference to,

means, or apparatus for use in printing letters, or other indicationsfor the indices of books, and other purposes, wherein letters or otherindications are printed in alternate, or equivalent arrangement ofcolors say one letter black as A and the next letter red as B and so on,and yet the printing is efiected rapidly and continuously. These lettersor in dications are preferably formed of vulcanized india rubber mountedon or secured to plates or surfaces of metal, while these again areborne by slides or supports arranged with capability of sliding in slotsor grooves or guideways which extend radially from the centralcompartment to the periphery of a wooden, or other wheel or circularbody of the appa ratus. This central compartment contains the hub inwhich the axis rotates to which the handle or support for the tool isattached.

,Upon each slide, orltype support is formed a projecting pin, orequivalent part, and upon the hub and against the wheel and slides; andso as to engage the pins, or equivalent parts on the slides, is mounteda plate, or disk,having on its inner face a snail, cam, volute or othereccentric or pattern groove, or surface into which the pins engage, orby which they,

or their equivalents are operated when the said plate is turnedrelatively to the wheel so as to cause the respective slides and thetype surfaces carried by them, to be protruded, or withdrawn from theirgrooves,

more or less and thereby to increase, or decrease the pitch of thewheel, or the relative spacings of the types apart. This turning of thisplate may be effected by a key, and the plate may be pressed to thewheel by a spring. The inking of the respective types with theirrespective colored inks is effected by means of rollers one to eachcolor each roller mounted on an axis borne by a spring, or other arm,which arms also carry projecting parts which each come in contact withcorrespondingly formed surfaces or patterns formed on or applied to thetypeplates and adapted to cause the colored ink roller to be liftedclear of the type surface not to be inked by it.

In place of causing the protrusion and re-- part the arch, with whicheach spring is formed is flattened each such spring becomes lengthenedas regards the distance of the end from the central support and theslide to each type pushed outwardly. I prefer to aifix to the snail, orequivalent part, for regulating the movements of the slides an indicatoradapted to co-operate with a scale so as to serve as a guide to theoperator in determining the amount of regulation desired.

In the drawings,Figure1 is a side elevation of my improved apparatus.Fig. 2 is a front elevation thereof. Fig. 3 is a detail of the scrollplate B, and Fig. 4 a section taken on the line a: 00 of Fig. 3. Fig. 5is a view showing the expansible wheel A, with the scrollplate, B,removed, and the slides D, without their letter plates, d. Fig. 6 is asection taken on the line y-y in Fig. 5. Fig. 7 shows a side elevationand plan of one of the letter slides D without the letter, E. Fig. 8shows a side view and plan of the spring plate, F. Fig. 9 is a diagramshowing the ink rolls, G, their lifting cams, H, and adjacent letterplates, (1. Fig. 10 is the key for altering the position of the parts.Figsxll and 12 are respectively a side elevation and section of amodified form of the expansible wheel, A; and Fig.13 shows an edge viewof another form of letter plate.

The object of my improved apparatus is to enable indices or other singleor multicolored indications to be printed in different lengths With onetool, which I effect by means of an expansible wheel supported betweenthe bif urcated ends of a forked holder having, at its other end asuitable handle. This fork also supports one, or more, ink-roll carryingarms, which are capable of movement about their pivotal connections.

The expansible wheel, A, consists mainly of a guide-plate, 0, having tworings, formed,

upon the same side of it, which are divided so as to form guide ways forthe letter slides D; these slideshave, at their outer ends, plates, d,which carry the letters E, their overlapping portions, (1 which engagethe ink-roll lifting cams, afterward I to be described, constituting themeans by which the proper color is selected for the letter borne by theplate of which it is a part. These letter slides, D, are each providedwith a pin, d, which, 00- operating with the spiral groove, 1), of thescroll plate, 13, constitute the means by which the wheel, A, isexpanded and contracted.

The scroll-plate B,is furnished with a spiral groove, 1), and a boss,I), which fits the central hole, 0', of the guide-plate, O, andis heldin that position by the spring-plate F(Fig. S) which is secured to thesaid boss by screws (not shown) which enter the holes,fand b the arms fof the said spring-plate, F, being set down, bear upon the back of theguideplate C, permitting it to be rotated, against their frictionalresistance, upon the bars, Z), but preventing its withdrawal; one of thearms, f*, is pointed and serves as a finger, which shows upon thegraduated scale, S, upon the back of the guide-plate, O, the length ofindex or other indication that the machine will print in a givenposition. The boss, 1), is bored to receive a bolt or pin, L, whichforms a bearing and is held by the forked end of the holder M.

The arms, N and O, are each provided at one end, with a roll, carried insuitable bearings and supplied with different colored inks, thesehearings consist of two downwardly bent ears, ll, 11 between which isplaced the pin about which the roll revolves, one of these cars, (Il,)is longer than its fellow and has formed upon its lower'edge a camsurface H which engages the over-lapping portions, 61 attached to theletters that the roll that this cam carries is not to ink and causes itto be lifted clear; the other ends of these arms are connected to thefork, M, by-the screws, 12 and 0, about which they are capable ofmovement, their outer ends being constrained to rest upon the letters E,or the overlapping portions (1 by the tension springs n and 0, which areconnected to the pins 01 and m; and o and m respectively.

It will be seen by reference to Fig. 2, that the letter plates, 02, areattached to the slides,

' pointing to the opposite side of the wheel to that to which the otherspoint, but when more than two colors are used the surfaces of theover-lapping portions, 61 are of varying shapes (see Fig. 13) the formof each being such as to lift all the inking rolls but the one fromwhich the letter, to which itis attached, is to receive its color, whosecam is permitted to pass through a channel, d lying in the same plane asthat occupied by itself; such a machine would have as many ink-rollcarrying arms as colors it printed.

In using the machine the operator, to adjust it to print the sizerequired, should hold the tool in such a manner as to prevent thescroll-plate, B, from moving and then, by means of the key K (Fig. .10)whose projections, 70, engage the holes, on the back of the guide-plate,0, move that partin the direction of one of the arrows, to cause theslides to go in or out, according to his requirements, until the finger,f points to the desired size on the graduated scale. I-Iaving thus setthe machine, he should place it 011 the edge of the book, or otherarticle to be printed upon, seeing that he begins in the correct place,whichis indicated by theImark, s, and wheel the tool along, until it hasmade one revolution, which in the case of abook it would have done bythe time the other edge was reached. It will be noticed that as thewheel is rotated the overlappingportions, or lifting plates, (1 of theletter-plate, d are caused to engage with the irregular cam S111? face,H, of all those inking rollsbut the one which is to ink the letterto'which it is attached, with the result that they areall lifted clearof the printing surface, but the one which supplies the right coloredink.

The modified form of expansible wheel shown in Figs. 11 and 12 consistof a disk or guide plate 0 and its letter slides D, of similarconstruction to that illustrated in Fig. 5 and a spring-plate R havingas many radial arched spring arms 1" as there are letter slides, whichis placed upon the boss T, after the washer t, and lastly the plate, P,is screwed onto the said boss T and completes this part. It will befound that by screwing the plateP farther into the boss T the archedsprings 1* whose pointed ends enter corresponding holes in the letterslides, being straightened will have their outer ends forced to agreater distance from the center and so eifect the expansion of thewheel; the washer, t, which is borne upon by the inner ends of theradial spring arms, a", equalizing the pressure, caused by theirstraightening, at each end of the let ter slides. The amount ofexpansion can be accurately gaged by the scale on the plate P which isused in conjunction with the mark '0 on one of the spring arms.

Having now particularly described and ascertained the nature of my saidinvention and in what manner the same is to be performed, I declare thatwhat I claim is 1. In an indexprinting implement, the combination of aholder provided with a handle, an expansible printing-wheel journaled inthe holder and consisting of a disk provided with radiating guide-wayscontaining slides provided with projections d and carryingletters orother characters, means for adjusting said slides, the arms N, 0 carriedon the wheel holder and provided with downwardly bent ears, the inkingrollers G mounted in said ears, and the cams H, one of which is formedon the lower end of one of the supporting ears of each inking roller,the said cams being each adapted to engage with the projections d on theslides carrying the letters or characters that are not to be inked bythe accompanying inking roll of that cam, to cause the said inkingrollto be lifted clear of those letters, substantially as described.

2. In an index printing implement, the combination of an expansibleprinting-wheel carrying a number of radially arranged printing slidesand having a scale by which the circumference of the printing surfacemay be accurately gaged, the ink rolls, and ink-roll carrying armsprovided with cams adapted to cooperate with projections on the printingslides to lift the inking rolls clear from those characters or lettersthat are not to be inked by a particular roll, and thereby eifect theprinting in difierent prearranged colors, substantially as described.

3. In an index printingimplement, the combination with the inking-rollsG, and cam devices carrying inking rolls of an expansible printing-wheelconsisting of the disk 0 having radial guide-ways, the letter carryingslides D each provided on one side with a pin d, and some of said slideshaving projections 01 the scroll plate 13 having a spiral groove 1)engaging said pins and provided with a boss I) fitting a central openingin the disk 0, the spring plate f, bolt L and holder M, substantially asdescribed.

In testimony whereof I, the said EDGAR AL- FRED GODDIN, have hereuntoset my hand this 5th day of January, 1894, t
